Okay so my 95 z28 383 camaro has had a missing problem that no shop or person can seem to find the source of the cause. We changed everything from opti, wires, plugs, etc,etc, coil. Recently the car was on a steep driveway idling and the problem missing went away after sitting and test drive. But then after a while it came back. Does anyone know what I should look for. Do u think maybee it could be a plug injector that was clogged or something.

 

Have you checked your fuel pressure?

 

yeah that's good. I had a shop check that out for me...

 

What was the result of their test?

 

Im not sure they didnt say. cause they did a bunch of things... They said all that was good. They think it might be a fuel injector that is clogged. They gauge reads 40psi fuel pressure idling. Not sure bout driving - havent paid attention to that.

 

what opti did you put in?

 

It had a msd but I took it out to see if it was the problem - the rotor was off so I just replaced it with a orignal stock oem one from the dealership

 

The shop unpluged the crane inginition box and the car runs allot better but theres a miss. It seems less spark it runs better. Plus two plugs keep getting fouled out.. Compression check is perfect... would this still indicate or lead to a fuel problem. maybee injector

 

Tell your parts changer, er shop, to swap the injectors from the fouling cylinders to other cylinders that are fine. Then run it and see if the problem moved with the injectors or stayed. If it moved, the problem was the injectors and some new ones will take care of it. If the problem stayed in the same cylinders, it was not the injectors.
